我似乎无法弄清楚这里发生了什么。我只获得一个NoReverseMatch只有一个项目，但所有其他类似的项目工作得很好。这是追溯。

以下是网址
url(r'^(?P<pk>\d+)/$',
SamView.as_view(),

)
url(r'^(?P<Sam>\d+)/John/view/(?P<John_version>\d+\.\d+)/$',
JohnViewer.as_view(),
name='john-view',
)
任何类似条目的URL都是/app/123/ or /app/1234/ etc.但是对于此特定条目，它返回500错误（回溯来自日志）并且似乎正在拾取第二个URL，而它应该是拿起第一个 - 就像/app/4321一样。这两个URL都适用于其他所有内容。
如果您需要任何其他信息，请与我们联系。感谢。

sam-view模板中有很多链接。其中一个是约翰观 - <button><a href="{% url 'john-view' sam=samtbl.id john_version=john.version.strip %}" target="_blank">HTML</a></button>。没有“倒退”。在两个观点中的任何一个。

你Sam get view应该是
def get(self, request,pk):
print "PK",pk # here is your id
return super(SamtView, self).get(request, pk)
我不知道你为什么使用位置（* args）和命名参数（** kwargs）？你的网址没有捕获它们。您的网址只是传递了一个名为pk
url(r'^(?P<pk>\d+)/$',
SamView.as_view(),
name='Sam-view',
)

解决了这个问题。检查了数据库，John_version设置为.1。但john-view网址是
url(r'^(?P<Sam>\d+)/John/view/(?P<John_version>\d+\.\d+)/$',
JohnViewer.as_view(),
name='john-view',
)
将其更改为0.1并且有效。
